Question

Ayuda, doy corona, porfavor si no me vas a ayudar no respondas

Answer 1

Respuesta:

Explicación paso a paso:

( 2/1 * [ 2/3 + 4/5 ] ) / ( [ 7/8 - (-1/2) ] * [ 2/3 + 6/5 ] ) =

= ( 2 * [ (2*5+3*4) /15 ] ) / ( [ 7/8 + 1/2 ] * (2*5+3*6) /15 ) =
= ( 2 * [ (2*5+3*4) /15 ] ) / ( [ 7*1+1*4 ] /8 * (2*5+3*6) /15 ) =

= ( 2 * (10+12) /15 ) / ( [ 7+4 ] /8 * (10+18) /15 ) =

= ( 2 * [ 22 /15 ] ) / ( 11 /8 * 28 /15 ) =

= ( 44 /15  ) / ( 11*28 /8*15 ) =

= ( 44 /15  ) / ( 308 /120 ) =

= ( 44*120 ) / ( 15*308 ) =

= 5.280 / 4.620 =

hallo el MCD para simplificar  ,  que es 660

simplifico por 660

( 2 * [ (2*5+3*4) /15 ] ) / ( [ 7/8 + 1/2 ] * (2*5+3*6) /15 ) = 8 / 7
